About Hennessy Research Associates

A Trusted Partner in Veterinary Vaccine Development

Hennessy Research Associates (HRA) helps animal health companies advance veterinary vaccine programs for the U.S. market.

As part of Kemin, HRA provides contract research, diagnostics, technical development, and manufacturing support designed to help partners move from concept to execution with greater clarity and confidence

Built on Applied Science

Our work is grounded in applied science with a practical focus on development outcomes. Research and technical activities are planned with manufacturing feasibility and regulatory expectations in mind, helping partners generate data that supports decisions and reduces rework later in development.

The goal is not just progress in the lab, but progress that is practical, transferable, and aligned with the needs of the program.

Designed for Collaboration

Veterinary vaccine development requires scientific, operational, and regulatory alignment. As programs move forward, gaps in capability, capacity, or U.S.-specific experience can create delays and additional risk.

HRA was built to work alongside internal teams—whether that means extending existing capabilities, supporting a specific development stage, or providing additional expertise where it matters most. Our role is to help partners move forward with clearer coordination, informed decisions, and dependable execution.
